Aplicabilidade da lignina no tratamento de resíduos aquosos

Abstract

Environmental pollution, especially water, is a serious problem that has been growing by the day due to various contaminants released in water resources as: heavy metals, dyes, domestic sewage, among others. In this sense, the term environmental sustainability has been increasingly commented in order to raise awareness to all of the risks to the environment and the human health. Within this context, lignin, third largest constituent assembly plant and biomass obtained from agro-industrial waste and pulp and paper industries, therefore lignocellulosic and biomass renewable resources, has introduced structural chemical properties that make it a promising material for removal of these pollutants in aqueous wastes. Thus, this work was conducted an overview about the potential use of lignin to the aqueous waste treatment, being possible to observe good performance this macromolecule, especially when modified, the removal of pollutants, such as dyes and heavy metals present in aqueous solution.
